Specification of Letters Patent Patented July 30, 1912.

Application filed March 9, 1911'. Serial nofietsasa To all whom it mayconcern:

subject of the German Emperor, residing in the city of Bethlehem, in thecounty of Northampton and State of Pennsylvania,

have invented new and useful Improvements in Charging-Machines for Coke-.Uvens oi" Gas-Furnaces, ofwhich the following is aspecification.

The resent invention relates to charging machines for coke ovens or gasfurnaces capablgof operating above the battery and.

equipped with mechanism for raising and lowering the ovendoors.

According tothis invention the charging car is so constructed "thattliecar frame or body leaves a free space at either end of the ovens, wiich enables the ascension pipes for the "gases of distillationissuing'from the coking chambers to be placed there. To this endbrackets or arms are extended from the upper part of the car ateitherside, on which are mounted rollers or drums to ceive the chains or ropesconnecting the ovendoors with the operating device provided on the car.The novel operating device earned on the car cons sts malnly ofa systemof hand or power driven long1tud1- nally movable rods or barsarrangeddongi tudinally'to the coking chambers ,and pref- 'erablyyertically above the discharge openings of the coal compartments of thecar: The rods or bars may be operated in different ways, eit'her asillustrated by way of an example in the drawing or, they may be providedwith a piston at one end and inclosed in cylinders to which. steam, airor a liquid under pressure is admitted, or they may be provided withteeth in which engages a driving wheel:

In thedrawing, Figure 1 shows a'cross section through a'battery of ovenswith the charging car in longitudinal elevation, Fig.

2, is a. plan view of Fig. 1, and Fig. 3' is a part section through thedevice for operating the oven doors.

Abovethe battery of ovensl are rails 2 on which the charging car 3 ispropelled. The car may be hand or power driven. The coal for chargingthe ovens is contained in compartments 4, at the botto-ni of which arefolding doors "or slides 5' for discharge. The car frame or body aswill-be seen leaves a free. space at both ends of the oven, where theascension pipes 6 are placed, which draw olf'the gases evolved in theovens. At

' parallel to the coking chambers.

the upper art of the car frame on both Be it known that I, WILLIAMFE-IOKS, a p

necting the oven doors 9 with theoperating device. on the car. Thedevice for raising and lowering the oven doors consists of two"longitudinally movable rods 10, arranged at the upper part of the carand on an axis an enlarged scale'in Fig. 3, the right-hand operated bya'sleeve 11 which is provided, with right and left hand thread engagingdrive 12 connected to either one of the motors 13. Suitably arrangedclutches allow either one of the motors 13 to be used for driving thecar or the device for raising and loweringv the oven doors. To preventclosed in a housing 14:.

The action of the apparatus is as fol; lows; The coal compartments 4 ofth'ecar, having been filled with coal, the car is run directly overone-of the ovens 1, the chains lowered and hooked to the oven doors 9.The operating device of the doors. is now started in the reverseddirection and the oven doors raised. The coke in the .oven may now bedischarged in any desired manner. The doors are then lowered, the'chains disconnected and raised again. The covers of the charging holesare now removed and the coal charge dumped into the oven by the foldingdoors 5. After charging; the oven, the covers for the charging. holesare 'put back in place.

' All operations of the apparatus can be started by simple actuating oflevers or equivalent means so that it can be handled by a single man. Iclaiin:-

1. In combination with a battery of coke ovens, or gas furnaces acharging car capable latter carried on the car,said operating de- (Shownon 5 rod 10, being broken away.) The rods are with similar thread out onthe rods.' The 70 the-admittance of dust the rods 10 are inso vicecomprising a pair of longitudinally movable rods arranged tosimultaneously 'or power operated laterallymovable rods or oars,-substantially as set forth.

'3. The combination with a car for voperating oven doors and arranged toleave spaces on top of the ovens atthe. door ends thereof foraccommodation of ascension pipes, of a hoisting mechanism on top of saidcar comprising longit udinally movable rods, means attached thereto forlifting the doors, guiding means for said lifting means, and means foroperating said rods. 7

4. The combination with a battery of coke ovens or gas retorts, of anapparatus for charging the ovens and operating the oven doors comprisinga car capable of traversing above the battery, the lower partof said carleaving a free spaceateither end of the ovensand the top ofthe carprovided with an extension the ends of which terminate in substantiallythe same vertical planes as the oven doors lie in, a hoisting devicecarried on said car, means for connecting said -hoisting device with thedoors of an oven, 36

ovens or gas retorts, of an apparatus for 40 operating the oven doors,comprising a car capable of traversing above the battery of ovens andleaving a space at either end thereof, a pair .of longitudinally movableoppositely threaded vrods carried by said car, a correspondinglythreaded sleeve in engagement there with, means for holding said sleeveagainst lateral movementin respect to saidrods, means carried by the carfor rotating said sleeve, a housing for said rods,

means for connecting said rods with the doors of an oven, and guidemeans to change the direction of travel of'aforesaid connecting meansbetween the rods and oven doors,

whereby upon rotation of said sleeve thesaid-rods will separate orapproach each other in said housing andcause said connecting means toraise or lower the oven doors.
